Tv has double image color red and a curl line on left upper corner also sometime in middle of tv it has line

This sounds like a problem with "convergence" of the TV. Convergence is the electronic aiming of the Red, Blue & Green projectors. Typical convergence problems look like double or triple images on part or all of the screen, wavy lines, curled edges, excessive red, green or blue color or tint, etc. Sometimes, convergence issues can be corrected in a menu setting of the TV that has to do with "Picture Settings" or "Advanced Settings".

If the colors are out of alignment a great deal or went out "all of a sudden" it will probably not be repairable via the menu adjustment described above - but is certainly worth trying.

If it does not straighten out with the menu adjustment, it will probably require replacement of the convergence integrated circuit(s) chips located in the TV. This was a big ticket repair years ago, but can be done sometimes for as little as $40 in parts. Don't let the low price fool you though.. It can easily take several hours (or more!) to access, remove & replace the components and reassemble the TV. Soldering skills are a must - and I'm not talking about soldering plumbing pipes here either. These are delicate electronic parts and need a 15 - 30 watt soldering iron and desoldering braid or solder ****** and LOTS of patience to perform CORRECTLY. As such, it is another "not a DIY project" unless you're willing to turn your TV into a large floor model paper weight. If you decide to attempt this repair, you should google your TV brand and model along with the term "convergence". Parts, costs and procedures vary by TV. Unplug the TV for a day or so before starting the work to let capacitors discharge fully - just to be safe. Lastly - don't forget the heat sink compound - it is an absolute *must*!

Coulor distortion at the top left of the screen

Hello jordan ashe,

This is an indication that the green CRT is having a convergence problem. This might be caused by the convergence amplifier or by the CRT. Does the rest of the picture look OK? and in addition can you supply a picture of your TV so as I can see what you are seeing and develop a proper diagnosis?

Thank you,

Left top and right top of screen curled, bottom middle of screen has a hump to it

Yes you need to repair the convergence circuit. If you know how to solder and use a meter this can be fixed easily by yourself. If you call a repairman to do it, it will run you $300-$500 depending on your area. Let me know if you can use a meter and solder and we can move forward with repairing you set.

Green semi-circle of lines on Samsung 55" HDTV (projection)

I believe i have the same problem myself. When my TV is on any of the Component Inputs without my DVD player turned on i usually get the normal green screen. But now that is a dip in the green at the top of the screen from the top left to almost the top right and black pushing down on the dip. Almost like a green curtain was sagging at the top and you can see the black behind it. It does this on every input and distorts every picture you see. The distorted picture has all the green slightly off from where the rest of the picture is and where the dip at the top of the screen is there is somtimes purple instead of black.

I know the basics of how the picture gets onto the screen and its my guess that the Green "gun" for lack of a better term and somhow come loose, or been missaligned to a great extent. I would love to find an answer to this problem, and anyones best guess as to how much a repair man will charge, just so i know the ballpark.

What you're describing is convergence and the amps need to be replaced... IK04 and Ik05 are two STK392-110 and Hitachi suggests replacing them with the STK392-150's for greater reliability..
If you're not too capable in electronics this is one to leave for the professionals. But at least you can call around and ask what each shop charges for replacing the convergence amps in this unit...
Hope this helps.

Convergence problem, lower left corner fixed green gun convergence bows upward

You have a componet out of tolerance in the green drive circuits, resistor or capacitor. If you have the service manual you should be able to take some raedings off the test points for the circuit and be able to track it down. I am enclosing a link where you can purchase the service manual for that set for 10.99. They will mail it to you unless you go back to the site and request that they email it to you by clicking on the contact us link. They also offer unlimited free support if you purchase your manual. I am one of their support techs. Hope this helps. Heres the link
